Which team will you be joining?

A Primer payment is worth so much more than a regular payment!

Our Acceptance team enables merchants to accept online payments as seamlessly as possible in any region using any payment method. 

This team is primarily responsible for: Checkout, Payment Processing, Payments API, Tokenization, BIN Data, 3D Secure, Developer Tools, Public Docs, Payment List & Timeline, Loyalty & Workflows Engine.

Reporting to an Engineering Manager, you’ll join a team of backend, frontend and mobile engineers all working together.

The team adopts a ‘you build it, you own it’ approach, working with infrastructure, doing their own testing and QA.

Our tech stack includes: Python, Typescript, React, AWS, Kubernetes and Terraform amongst lots of other things.

🔍 What will you be doing? 

• Designing and implementing core backend services for high performance, complex distributed systems

• Driving and using modern development practices such as BDD and TDD would be highly beneficial

• Creating clear, modern, well tested code

• Collaborating across teams in a product-driven environment 

• Taking ownership of key technology decisions, building for scale and optimising for output

• Conducting code reviews and continuously look at ways of improving our ways of working

• Creating detailed internal documentation for the projects you work on

👀 What we’d love to see: 

• In-depth understanding of the entire development process (design, development and deployment)

• Knowledge of building developer frameworks and workflows, allowing both customers and third-parties to integrate as seamlessly as possible

• Experience in Python is advantageous (it's what we use!) but we have had success hiring engineers of any technical background and understand that people can adapt

• Highly motivated self-starter who values autonomy and getting things done

• Excellent verbal and written communication skills

• Payments knowledge, always looking for ways to optimise our merchant developer experience

🚫 You may not like it here if:

• You enjoy working in an office-setting, we are remote-first and always will be!

• You are not comfortable with shifting context and navigating ambiguity

• You don’t enjoy testing your code, we have no testers or QA’s here at Primer

PLEASE NOTE: Our engineering teams work fully remotely across Europe but we are focusing our hiring strategy on these locations: UK 🇬🇧, Hungary 🇭🇺, Romania 🇷🇴, Serbia 🇷🇸, Turkey 🇹🇷, Bosnia 🇧🇦, and Greece 🇬🇷.

Unfortunately we are unable to offer sponsorships or relocation packages at this time.
